A diagram that explains the generation of the computer can be found on the Scribd website. First generation computers used vacuum tubes.
25000 vacuum tubes
It used 5200 vacuum tubes.
This would depend on the type of vacuum tubes needed. Any car part store will carry vacuum tubes for a car, general stores carry vacuum tubes for household vacuums, and AC part stores will carry vacuum tubes for the AC/Heating system of a house.?æ
Inventor Alan Turing used computers that used vacuum tubes. Before the invention of transistors vacuum tubes were used for electronics.
vacuum tubes help us today with many things. the most important 1 is techology. If we didn't have vacuum tubes we wouldn't have computers. just thik of a life with out computers or t.v. vacuum tubes are also used in radios. so if vacuum tubes hadn't been invented we would not be able to use all the techology we use today.=]
who made the vacuum tubes
No, there are some cold cathode vacuum tubes. These do not light.
They were called vacuum tubes.
ENIAC was the first digital general purpose computer, built in 1946, and with 17,468 vacuum tubes. The Illiac I, the first computer built and owned by a US educational institution, had 2800 vacuum tubes. The IBM 604 had about 2000 vacuum tubes.
Modern devices use integrated circuits instead of vacuum tubes because integrated circuits occupy less space than vacuum tubes, are more efficient, consumes less energy and are more reliable than vacuum tubes.
Vacuum tubes were first replaced by transistors, and later by integrated circuits.
The ENIAC has 17,468 vacuum tubes. These tubes were the first technology that made computers function. Modern computers do not use this technology.
Radio vacuum tubes. Eventually computer grade vacuum tubes were developed that improved reliability.
Vacuum tubes vary from thumb size to larger than most people. Integrated circuits or ICs' are the size of you little finger nail. There was nothing worth remembering before vacuum tubes.
An integrated circuit uses transistors instead of vacuum tubes. Transistors and vacuum tubes can do the same things, in terms of how they alter the flow of an electric current in a circuit, however, vacuum tubes are much larger, and they are also much less reliable, since they will eventually burn out, unlike transistors. So with transistors you can do a lot more. Even though the earliest electronic computer (ENIAC) was made with vacuum tubes, nobody today would want to attempt to build a computer with vacuum tubes.
Vacuum is required in vacuum tubes, because they are used to manipulate a flow of electrons between the cathode and the plate (anode). Air would get in the way, and it would also contribute to early burnout of the filament.
The main disadvantage of vacuum tubes is that they require bulky power supplies. As there is high voltage electric shock hazard is also there.

The Harvard Mark IV had about 4000 tubes.
It is a cleaner machine
